Frequently Asked Questions
An industrial check valve allows flow in only one direction and closes automatically when reverse flow attempts to move through a pipeline. This helps protect pumps, piping, meters, and system components while reducing the risk of backflow and water hammer.
Selection depends on application pressure, fluid type, material compatibility, installation orientation, certification requirements, and end connection style. Matching system conditions with the appropriate series ensures smooth operation and reliability.
They are used in waterworks, wastewater facilities, fire protection systems, industrial plants, commercial plumbing environments, and agricultural irrigation systems.
